To 14/! whom, it may concern..-

Be it known. that we, PHINEAS ll. nioiins, Jr, and ()nsnnas 'l. X. Anans. citizens of the United States, residing at l1icago,lllinois,

have invented certain new and useful Improvements in Apparatus for [*se in Decoin- 1 posing Metallic Salts and Dcsulphnrizing Ores, of which the following is a specification.

The object of our invention is to make an apparatus that will operate to mechanically decompose chemical compounds, metallic salts, and desnlpliurize ores or their resulting material, when the substances treated are in a molten state, by the action of centrifugal force; and our invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figure l isa vertical section of the upper portion of the apparatus, showing the running-gear in elevation. Fig. 2 is a vertical section taken in the line 2 of Fig. 1, showing the running-gear and an oilcup; and $3 is a modification of the running-gear.

In making our improved apparatus for decomposing chemical compounds, metallic inner lining, L.

Between the shell and the lining we prefer to interpose a packing, C, of 5 non-heat-conducting material, so that the conduction of heat from the interior of the vessel, when it is receiving; molten material in operation will be as little as possible. This nonheat-conductin g packing may entirely fill the space between the shell and the lining from top to bottom or such portions of the space as may be desirable. For instance, the outer sur face of the lining, which is of course made of a size and shape to admit it to the interior of the surrounding shell, may be provided with channels, grooves, or indentations, into which the packing may be placed. As shown in Fig. 1, the lining is provided with annular ribs 1), which serve to divide the space between the lining and the shell into a number of annular channels or grooves, in which the packing is arranged. The use of these annular ribs or flanges will serve to strengthen the lining and enable it to withstand a greater internal pressure than when they are omitted.

As a further means of strengthening the re cciving-vesscl and providing against its ex plosion or instantaneously going to pieces in case it should be subjected to too rapid rota tion or to too great a strain in operation, we prefer to inelose it in a cover or envelope, E, of strong wire wrapped tightly around its outside in many coils or layers as may be desired. "0 also prefer to wrap the curbing with wire in the same way.

The neck or mouth of the receiving-vessel, the arrangement of its bottom, the curb surrounding the receiving-vessel, the means for removing the lighter particles of the material treated after they have been thrown. out of the mouth of the receiving-vessel by the action of centrifugal force, the method of attaching the actuatingshaft F to the receiving-vessel, so as to rotate it, and the arrangement of a joint, G, to permit the upper portion of the actuating-shaft to have sufficient play toaccommodate itself to the lateral vibration caused by the rotation of the receiving-vessel, as they do not separately form subject-matter of claims in this application, need not be minutely described in detail.

The lower end or portion of the actuatingshaft by which we mean that portion that engages with the bcarin g by which the shaft and receiving-vessel are supported and rotated) rests in a divided bearing containing one or more sections which rotate in the same direction as the rotation of the shaft, but at a loss rate of speed.

In describing the divided bearing for the actuating-shaft we will begin with the stationary port-ion H of the bearing. This section of the bearing is located at the bottom and does not rotate with the rotation of the shaft. It.-

preferably provided with a T- shaped head having a hardened ring or track, 72., around its upper surface. The next section, I, of the bearing, immediately above the stationary piece H, is preferably provided with a channel or groove containing a hardened surface or track, '1', adapted to receive a number of balls or rollers and retain them in place on the hardened track 7: l'ietwccn the sections II and I. This section of the bearing is also preferably provided with a beltsurface, i, open at its ends, so that its lower portion will fit over the top portion of the section ll, as shown in Fig. 2. The bearing I is also preferably provided with a T-shaped upward extension having a hardened track or surface, 1 This upward extension stands some distance above the top of the pulley or belt-surface. Another section, J, having a track or hardened surface, j, adapted to receive and retain a number of balls or rollers between it and the hardened track or surface L, is placed immediately above the section I. This section J is provided with a belt-surface, 3', extending both upward and downward.

The ends are open, so that the portion of belt-,

surface extending downward may surround the upward T-shaped extension 011 the section I. The upper portion of the section J is also provided with a hardened track or surface, j, adapted to receive balls or rollers, and a block, K, having a hardened track or surface, 7c, on its under side, adapted to reston the balls or rollers in the upper part of the section J, is inserted through the open top of the section, as shown in Fig. 2. The actuating-shaft F is provided with a shoulder located in and resting on the piece K,to which it may be fixed in any suitable manner, so that the piece K and the shaft F will rot-ate together. This piece K thus receives the weight of the actuating-shaft and the parts connected with, resting on, and revolving with the same.

As shown in Fi 9, the different sections of the bearing are held in line, and provision is made for oiling or lubricating them by means of a perforated hollow extension of the shaft F, diminished in diameter, which passes down through them. The pulley I. is fixed to the actuating-shaft F, as shown in Fig. 2, or in any other suitable manner, so as to rotate the same as it revolves. It is connected with a power-shaft, M, driven by the power of the works by means of a belt connecting it with the pulley Z. The pulley or beltsurfaces i J are also connected with the pulleys or beltsurfaces I J, mounted on and rotating with the power-shaft M. These pulleys are proportion ed to each other so that the sections I and J of the bearing will be rotated i'n'the direction of the rotation of the shaft, but at a less rate of speed.

In Fig. 3 the aetuating-shaft F rests in a block, 0, to which it is fixed, and which retates with it. This block rests upon a number of rollers, as shown in Fig. 3, which in turn rest upon a block or section, I. The block or section I also rests upon a number of rollers, as shown in F1 23, which in turn rest upon a stationary block, Q. The section of the bearing P is fixed to a shaft, F, provided with a pulley, F", to which it is fixed,

and the pulley F intended to be connected with the pulley I on the power-shaft whenever the modification shown in Fig. 3 is used.

In operation the pulley L is rotated by the belt connecting it with the pulley] on the power-shaft, and as it revolves it rotatesthe actuating-shaft and the receiving-vessel, into which the molten material to be treated is introduced. As the lower end of the actuatingshaft is rotated, it carries around with it the block K. As this block sustains the weight of the actuating-shaft and the parts resting upon and rotating with it, it bears upon the balls or rollers located in the upper portion of the section J. This causes the section J to bear upon the rollers arranged in its lower portion and on the T-shaped upward extension of the section I. This causes the section I to bear upon the rollers located in its lower portion and on the upward T- shaped extension of the stationary block H. As the part K revolves with the same speed as the shaft, there would be produced a friction-speed equal to the rotation of the shaft; but as the section J rotates in the same direction, but at a less rate of speed, the frictionspeed of the piece K is diminished. In like manner, as the section J revolves, but at a still lower rate of speed, the friction of the section J is diminished; and the friction of all of the parts is still further diminished by the presence and rotation. of the balls or rollers located between them. \Vhere the modification shown in Fig. 3 is used, the weight of the actuatingshaft and the superimposed parts rests on the block 0, which rotates with the shaft. The section P on the upper part of the shaft F rotates in the same direction, but with a less rate of speed, and thus divides the frictionspeed of the block 0. The friction of both of these parts is still further diminished by the presence of the rollers between them, as shown in Fig. 3. In this way we are able to avoid all injurious friction while rotating the actuating-shaft and the receivingessel at a very great rate of speed.

\Ve do not wish to limit ourselves to the precise details of construction in securing the divided roller-bearing shown in the drawings, as in many respects the details may be varied without departing from the essential features of the invention, which may be explained as a bearing comprising one or more revoluble sections having tracks, grooves, or bed-surfaces adapted to permit of balls or rollers being ar ranged so as to roll on and between them, and at the same time in their rotation carrying one or more series of rollers or balls at the other end which are adapted to retain and carry the weight of another revoluble section arranged. to be revolved and carried upon and by them, with means for revolving the various sections of the bearing independently of each other and at a less rate of speed than that at which the actuating-shaft and the receiving-vessel rotate.

In the specification and claims, when we speak of a number of sections of the bearing we desire to be understood as meaning one or more intermediate or rotating sections, and in those claims which do not call for any means for rotating the various sections of the bearing we mean to include a construction in which the sections, or some of them, are left free to rotate as the rotation of the actuatingshaft may produce that effect.

\Yhat we regard as new, and desire to secure by Letters Patent, is-

1. In an apparatus for decomposing metallie salts or salts of metals and desulphurizingores when in a molten state, the combination of a revoluble receiving-vessel adapted to receive molten material to be treated, comprising a surrounding shell or case provided with an incasing cover or envelope of wire wrapped or coiled around the same, and a lining havin g an exterior of a size and shape to admit it to the interior of the surrounding shell or case, and a non-heat-condnoting packing interposed between the lining and the surrounding shell or case, and means for rotating the receiving-vessel, substantially as described.
